南河湾之诉

有村南河湾,远近美名扬。村西出清泉,玉带绕村行。河岸杨柳绿,人杰物产丰。姑娘争嫁来,小伙精气神。突然有一天,“二懒”变能人。投机赚了钱,还想钱滚钱。村旁建焦厂,竖起高烟囱。黑烟空中飘,污水河中排。杨柳秃了枝,青蛙失了声。麻雀成乌鸦,小猪倒立鬃。清泉不再清,玉带变臭沟。浇地地板结,种菜菜烂根。气味呛眼鼻,烟尘积厚层。热天不敢开窗户,屋外不能晾衣巾。乡亲身体日渐弱,咳嗽气短疾病生。邻村姑娘不嫁来,本村姑娘嫁他乡。可怜祖留祥和地,如今变成破落村。     

秦皇岛市水环境现状与恢复

秦皇岛地区原始自然环境优越,多年来,不正当的人为活动、环境恶化趋势明显,也直接干扰与影响着水的良性循环。现状水环境:河流基流渐小,并季节性断流,坑塘减少,湿地萎缩水土流失,洪径增大。地下水位下降,水量减少,承压水无序开采,污净比失衡,河流承栽力降低。地下水垂直污染面扩大,点、面、垃圾污染源趋重。联通青一洋、石一起,实施水资源再分配。优化配置城乡用水。重视地下水源地建设,联合调度地表、地下水源。谨慎开发承压水。植树造林、涵养水分。注重防风林带建设,改善田间小气候。严控地下水采量,防止土壤旱化。搞好坑塘建设,解决乡镇污水出路与净化。保护湿地,促进水的良性循环。深度处理废污水.使之资源化。从源头抓好城市三大水源地污染源.察勘储备新地下水源地。改良恢复水环境,保障水资源循环利用。     

环保文娱

孟树国江南有奇峰,高耸入云端。万山拜其下,孤云卧此间。古稀花甲者,汇聚六十三。胸怀国策志,考察皖名山。先访翡翠谷,继至老龙潭。苍松枝如冠,绿竹叶似帆。清池勤沐日,花雨巧耕峦。缆车遨云海,铁屋落霞栅。雄鹰搏无忌,鹃鸟啼不烦。探秘排云坳,深研北海湾。考究光明顶,遥思玉屏     

篱笆墙的影子

正最近忙,顾不上看书,荒废了几天,终于静下来。扯上一本林徽因的作品,把手机关掉,得把阅读补回来。哪里浪费的从哪里补,我有时候很拧巴。"真正的平静,不是避开车马喧嚣,而是在心中修篱种菊。"看到林徽因这句话,一个激灵。篱,篱笆也。乡村,不缺篱笆。立几根木桩,相当于经线,桩与桩之间,竹片一前一后错开绞上去,像密密的纬线。这种篱笆结实,可高可矮,可长     

爱—绿十快

萝卜白菜,各有所爱。有人迷官,有人恋财。吾独爱绿,岂不快哉。生于河边,长于乡下。村前绿树成林,村后绿水喧哗;村内绿荫匝地,村外绿满天涯。岂不快哉。诗词含绿,意趣盎然。过目成诵,生机无限:“东风吹水绿参差”,“春风又绿江南岸”,“日出江花红胜火,春来江水绿如蓝。”岂不快哉。《青纱帐,甘蔗林》,《青枝绿叶》《绿灵魂》。《情满青山》《江南春》,架上书刊绿成阵。绿色诗行绿     

向大海

<正>1秋风响,蟹脚痒。蟹脚为何痒？有人说,是蟹在长肉,关节胀痛;有人说,是蟹生性好动,淘气顽皮。都不是。蟹脚痒,是蟹要离家出走,奔向遥远的大海。人们只知道大雁每年会迁徙,却不知河蟹每年也要洄游。秋来时,大雁要飞越千山万水,到温暖的南方去。而河蟹也要爬行千里、万里,到广阔的大海去。河蟹要从小河爬进大河,再从大河爬进大江,最后抵达大海。在江海交汇处,交配产卵,繁衍后代。     

酒逢知己 随意好

陪了几回客,慢慢地,我发现酒桌上的学问不是喝酒而是敬酒。中国的语言可谓丰富多彩,到了酒桌上,更是妙趣横生。高水平的劝酒者其劝术使你不得不喝,不能不醉。你听:“来,感情浅舔一舔,感情深一口闷。”这是第一杯。“好事成双呀”,又劝进第二杯。如此这般,先让你飘飘然。主人说罢“随便”,在座的便自选对象,各显神通。你听:“来,干了。”此是见面酒。“老赵,好长时间没在一起聚聚了,来两杯。”这是“叙旧酒”。“来,老陈高升了……还有小朱喜得贵子,咱们一块干。”此谓“祝贺     

查污染有感

长途奔袭,登高观看,不由怒气冲天!远近星星点点,污染连成片。蓝天白云何处?周遭烟雾笼幔,景物依稀不见。再闯工厂查看,粉尘迷眼,废渣漫延,烟囱吐黑烟,污水暗管排泄。如此猖獗行为,明显乏力监管。锦绣山河遭涂炭,父老乡亲受熬煎。油皮、地瘩老板,损众利己只为钱。纵有资产百千万,如此缺德心当颤。再问当政父母官,良心当     

芙蓉花里寻

这是一次匆忙的行走,去往蜀国之都。成都,是一个悠远的梦,适合在如水的夜色中到来。旅途的夜晚,我总是异常清醒。犹记得,黎明前经过一处隧道,本是漆黑一片,慢慢地看到远处的光,那一瞬间,从毛孔到血液都很是感动。那微光引领着日光抵达世界,于是天开始光亮,世界苏醒。我却沉沉睡去。抵达成都,天已黑尽。看到笑意盈盈的浅浅站在我面前,我知道我已来到梦的中央。次日。睁开眼睛,天色已是大亮。

Evaluation of municipal solid waste composting kinetics

Most modern municipal solid waste (MSW) composting operations have emphasized the enhancement of decomposition of the organic fraction of the waste to comply with strict environmental regulations. This can be achieved once the composting process kinetics are well understood. This study examined process kinetics through experimentation with bench-scale reactors under controlled composting conditions to show the interdependence between biological, chemical and physical factors during composting of MSW. The effects of temperature, moisture content, waste particle size and carbon to nitrogen (C/N) ratio on process kinetics were evaluated. The results obtained revealed that these factors should be carefully controlled in order to achieve optimum process performance. It has been found that the organic matter degradation during composting follows a first-order kinetic model.

The design and use of strategic planning arenas

This paper takes a close look at communication, process, power and institutional arrangements in the context of strategic planning. It introduces an eight step process for structuring strategic thinking and acting and develops the concept of “arenas” as a very influential — yet often very subtle — exercise of power over the course of a strategic planning process.     

Environmental Impact Evaluation Model for Industrial Processes

This paper proposes a model to evaluate the environmental impact of manufacturing processes. This model uses the potency factor approach to classify environmental impacts into five ecological health impact groups and uses their toxicological, cancer, and physical effects as the bases to rate the seven groups of human health impacts. The environmental impacts in each impact group are reported, and their hazard scores on ecological and human health are determined. The model also generates a single score for the overall environmental impacts of a process. This single score system helps to identify, among all the viable processes, which is the most environmentally friendly process. This model can serve as a tool to highlight the potential environmental hazards of process operations and to provide information about environmental performance for decision making. The model has been developed into a computer software program, Environmental Impact Evaluation System, and is demonstrated by using the processes employed for the manufacture of paper bags.
